26 Claims. (Cl. 12m-43W This` invention relates to finishing machines Y and is herein illustrated as embodied in a heeliinishirgmachine of the type disclosed in Letters Patent of the United StatesNo. 1,943,308,`grant l ed January 16, 1934, upon an application filed in the name of Henry B. Greenough.

It is, customary in nishing heels or" ifnanytypesl of shoes to decorate their peripheral surfaces by forming thereabout rows oi indentations, which rowsare parallel in each casete the rand crease andwhich usually terminate at opposite sides of the heel near the breast corners. As the angle of a heel surface to be thus indented with respect to the treadl surface varies not. only'lin diierent shoes butzalsoat difer'entpoints 'about `the perpheryoi the heel' of practicallyany'shoe,

it is `alziparent that if uniformity. in the length of the indentations at all parts of thepheel is to be obtained, the relative positions of the in- `denting tool and the heel must be variedas fthe l point oi operation of the toolv on the theel is transferred thereabout.

Heretoiore such relative positioning of the tool the Work, especially in connection withthe indenting of'heels as distinguished from the infdenting of a sole marginor. welt, for example; has been eiectedby the operators varying the position of the shoe ,with respect to thetool so as to effect completecontact heightwise of ,the shoe between it and the tool. Accordingly the uniformity of the indenting operation fvaried ap-V preciably and dependedto a great extentori the `the attention given to his Work.

ability oi the operator, .his state of fatigue In View ofthe foregoing Ya general object of nthe invention is to improve and expedite the` in denting operation by rendering the tool Iseli# positioning. To this endl the invention contemplates the provision, in a heel-finishing machine,

`of an indentingtool mounted for bodily swinging movement, and' means mounted to engage a part' While `swinging `movement of the indenting tool could occur about an axis disposed between thev tool and the positioningmeans, inthe illustrated construction it occurs about a tangent to the operating surface of the-tool at the operating point as an axis and, accordinglmlthe pressure of the work against it isiineiieetual to alter its position. However, in accordance with anctherieature of the invention,` means is provided, `in'cbmbination Withthetool and `posiand 'ioning means referred to above, for Vyieldingly urging' thertool `toviardfone extreme of its swing; ing movement; New, as a resultv of presenting the reel surface to be indented to the -tool'and the positioning means, the` latter, againstgwhich the heel surface is held; is actuated by the movenient or the heel surface into engagementwitlr;

the tool' andcauses, the indentingd wheel to be so positioned 'as to havecomplete' Contact with the `heel as described above. in mostinstanes peripheral heel surfaces are substantially straight heightwise thereof., but they may alsobe curved, as inthe case oijthe heels` of some Womens shoes which are indentedf It is therefore-to be understood that the invention comprehends any arrangement ciV a tool and positioningfmeans or guide, the operativesuriace of which issubstantially intersected bythe operativeAsurface-o'f the tool when extended.

The `features ofy the invention as described above" have application not on-lyin-connection` with machines to which thezwork is presented by the operator, but also-the machines-'in which the workis held and presentedfto tools inechanically as by aY jack, forexafmple. l p

`Invention is to be recognized, therefcre` in the provision, inl a finishinginac hine,l of the com bination of an indenting toolhand4 means for jacking a shoe, the tool and jacking means being relatively movable toallow` the pointY of operation ei `the tool on-theheel to be transterred thereabout. It ,willr now" be apparent that whether a shoe is manually or mechanically pre- Ysented# to a tool which isselfpositioniiig, in actothe upper and on a section ofthe heel known as therand; As every heel doeslnotcomprisea rand, strictlyspeaking, it is to'be understood that 'the termuhandwasused hereinisapplied tothe uppermost section of a heel adjacent lto the upper i to which indentations are 'commonly applied and which forms a lower boundary of the gap between the heel andadjacent portiono'f the upper, which gapislcornrnonly known as thelrand crease. vlrequentlyytherrnarginal `portion of the heel which i* bounds the rand creaseis beveled slightly for decorative purposes, this beveled suriac-zl as well as` the peripheral surface of the heel being burnished in the nished shoe. Y It Vis apparent that the proper relative heightwise position of either a rand-burnishing or indenting tool and the heel to be operated upon is essential in order to insure that the rand will be well burnished without injuring the upper, or that the' row of indentations shall be applied about' the periphery of the heel at all points equidistant from the rand crease. Accordingly, it is anotherimportant object of the invention to insure that the movement of the point of operation of such a tool about the heel shall occur in a plane which is predetermined definitely with respect to the rand or the rand crease. To this end, there is provided, combination with a tool for operating upon the rand of a heel,` improved shoe-jacking means by the use of whichV a shoe can be jacked in. a position which is predetermined heightwise withreference to the actual part of the shoe which is to be operated upon. In the' illustrated machine, this jacking means comprises shoe-positioning members shaped and arranged to engage the shoe within the rand crease adjacent to the heel at opposite sides thereof, the rand-engaging surfaces of the members and the operating surface of said tool being disposed at the same height or in predetermined heightwise relation to each other. The jacking means also comprises cooperating clamping members for applying jacking pressure to the heel part of the shoe.

These and other features of the invention will appear more fully from the following description when read in connection with the accompanying drawings and will be pointed out in the appended claims.

With reference to Fig. l of the drawings, at the center of a frame I4 (this member as illustrated in the Letters Patent referred to above has the same reference character) is rotatably mounted a jack carrier I6 and a spider I8 (the corresponding parts in the machine illustrated in the aforesaid Letters Patent are designated by the numerals 20 and 22 respectively), the jack carrier and spider each having the same number of arms provided with shoe-jacking instrumentalities at their ends. The jack carrier I6 and spider I8 are rotatably mounted so as to carry the shoes clamped therebetween progressively to various operating stations, of which the indenting and rand-burnishing station illustrated herein may be one, and also to cause the sides of the heels to be moved relatively to the tools to cause the sides of the heels to be operated upon. Between the last-mentioned movements the carrier IB and spider I8 remain stationary while the work is ro tated about the axis of the jack to cause the rearmost portion of the heel to be presented to the operating tools.

In the illustrated construction, a shoe 2O the heel of which is to be indented and burnished along the rand is clamped between opposite arms of the spider I8 and jack carrier it by an abutment 22 adapted to engage the tread surface of the heel and a clamping member 26. shaped to engage the top of the heel part of the last. The clamping member 24 is constituted by a U-shaped slide mounted for vertical movement with respect to a spindle 26 in slideways formed at cach side of the head of the spindle. A helical spring 2 normally holds the clamping member 24 in its extreme upper position, which is determined by a screw 29 extending between the arms of the clamping member 25': and adapted to engage the lower end of the head of the jack spindle 26 (the corresponding part as disclosed in the aforesaid Letters Patent being designated 48). The abutment 22 is carried by a shaft 28 which is rotatably mounted in the spider` IS- coaxially with the jack spindle 26, which also is rotatably mounted in the jack carrier I6 and which is rotated in the manner referred to above by a gear train 30, as described in the aforesaid Letters Patent.

The operating tools in the illustrated embodiment of the invention comprise an indenting tool 32 and an oscillating rand burnishing tool 34 which are carried by a frame 36 in which is rotatably mounted a drive shaft 38 for operating the burnishing tool. The frame 36 and associated parts are yieldingly supported by an H-shaped link 39 which is pivotally mounted on a block 40 and which is supported by a spring 4 I. The block is mounted for heightwise adjustment on an arm 42 (this member being designated in the aforesaid Letters Patent by the numeral 4G). As in my prior machine, the arm 42 at its lower end (not shown) is pivotally mounted on the frame Iii so as to allow the tool to be moved into and out of engagement with a shoe carried by the jack. Similarly, as in my prior construction, the drive shaft 38 is rotatably mounted near the base of the arm 42 so as to allow angular movement between the shaft 33 and the arm 42. The arm 42 is normally urged toward the center of the machine to cause the tool to be held against Y the heel by means of a spring 44 which, by means of eye bolts, is connected to the arm [i2 and the frame I4; and the arm 42 is moved to carry the operating tools away from the shoe when it is desired to move the shoes between stations by a v bell-crank-operated link 46 which is pivoted to an extension 48 of the arm 42, the parts corresponding to which in the machine of the aforesaid Letters Patent will be readily distinguished by reference thereto.

As pointed out above, in holding a shoe for a rand-burnshing and heel-inrichting operation, it is desirable that the rand crease or rand itself should be positioned heightwise deiinitely with respect to the rand-burnishing tool, and preferably at practically the same height. To this end, the invention contemplates the positioning of a shoe with reference to the rand or rand crease itself so that variations in the height of heels will not affect the proper heightwise positioning of the rand crease or rand with respect to the pressure, and then jacking'theshoewithout mov; fing it from 1its 'xed position. The lshoe ll Lis herein illustrated as being thus positioned 4by rand-lcrease-entering `jiiiigers tfand 52 are motmtejd respectively'on pivots -ll antlt care ri'ed by Ya support '158.

The serrated surfaces of the wedge il and the plate lili] cooperate to insure that the wedgev Ilfl will be held releasably in whatever position to which it is moved by the operator and at the same time allow the wedge to be readily moved back andforth. As illustrated in Fig. 2, the wedge tilt is disposed between twoof the studs 98 and has a slot lii through which the third stud 93 extends. The studs 98 form a slideway iorthe Wedge IEM, the latter being yieldingly urged to ward one extreme of its limited movement by a light spring ll yone end of which bears against that stud ile which Vextends through the recess To an extension li i6 on the forwardend ofV the supp-ort il?) is: attached a brace H2 the lowerend of which is mounted in acollar H4 which is mounted to rotate with the jack spindle 2t in the end of the arm it of the jack carrier.

" The `jacking of the shoe in the illustrated devicefis eected by raisingthe spindle 25 which Y preferably can be accomplished in the same way as in the machine disclosed in the aforesaid Letters PatentV (namely, as a result of the jacking plate B8 being elevated in Contact with the lower end of the jack spindle V2t while `at the loading station) .Y When the jack spindle sthus elevated, the spring il is 'compressed until the desired clamping pressure is exerted upon the heel part of the shoe. Thereafter, as pressure on the jack spindle 2t is released, the latter is locked in its highest position by means of a springhctuated dog l lt (corresponding to that part designated by the numeral in the aforesaid Letters Patent).

The member |39 can be clamped in any desired adjusted position by means of screws |32 and |34 which are threaded in and abut respectively the frame 35. The swinging movement of the bearing member |22 in a clockwise direction (Fig. 5) is limited by a. bar |35 connecting the lower ends of the arms E26, the outer ends of which bar |36 are spaced from the sides of recesses in the arms of the member |35. The bearing member |22 also is yieldingly urged toward one extreme position of its limited movement by a spring |38 which extends between the middle of the bar |35 and a pin |46 fined in the upper end of the frame 36. rT "he bearing member |22 being adjustable about substantially a tangent to the operating surface of the indenting tool 32-at the operating point, pressure of the work against the indenting tool alone is ineffectual to cause any movement of the bearing member |22 away from its extreme position and against the tension of the spring |33. However, the indenting wheel 32 is so positioned as to have complete heightwise contact at the operating point with the heel surface presented thereto by means of a guide in the form of a roll |42 having a cylindrical face, as illustrated in Figs. 5 and 6, or a curved face, as illustrated in l, and which is mounted to rotate freely on the sleeve |26 as a journal. Therefore, as will be more fully described later, as the indenting wheel is brought into engagement with the heel surface to be indented, the roll |42 first engages the heel surface and causes the indenting wheel 32 to be swung into the desired angular relation with respect to the heel surface. The indenting tool 32 and roll |42, as illustrated in Figs. 5, 6 and 8, are shaped and arranged to operate upon a heel the peripheral surface of which is substantially straight heightwise thereof, but it is to be understood that the shape of the roll and wheel can be modified in accordance with the heightwise contour of the heel to be burnished so that they have the curved form which they are illustrated as having in Fig. 1, forexample, whereby they are adapted for operating upon a heel which has a heightwise curvature. In any case, the guide roll |42 and the indenting wheel 32 are so shaped and arranged that the element of the periphery of the indenting wheel at the operating point, when extended, intersects the work-engaging surface of the roll |42, thereby insuring complete heightwise contact between the wheel and the heel surface to be indented when both the wheel and the guide are in contact with the heel surface.

The rand-burnishing tool 34 has a, lip |44 shaped to be inserted in the rand crease and having a burnishing surface which may be beveled if desired and adapted to engage the margin of the rand. The tool 34 is attached to the ends of an oscillating yoke |46 which is pivoted to the frame 36 on a stud |48. The sides of the yoke |46 slidably embrace a block |50 to which is imparted a circular movement by an eccentric |52 formed on the upper end of a sleeve |54 which is splined to the shaft 38 by means of a key |56. It is apparent that as the drive shaft 38 is rotated only those components of the motion of the eccentric |52 which extend concentrically with respect to the stud |48 impart any movement to the yoke |46 which, therefore, is oscillated as the drive shaft 38 rotates. The sleeve |54 is supported at its lower end by the frame 35 and has a flange |58 below the eccentric |52 for supporting the block |50 and yoke |46. If desired, the tool 34 can be heated by a flame from a gas pipe |60 carried by a pair of studs |62 one of which is attached to the frame 36.

The illustrative embodiment of the invention having been described, its use and operation will now be explained. Assuming that work is to be operated upon for which the jack has not been adjusted, the shaft 28 is first raised, the wedge 04 being in the position in which it is illustrated in Fig. 1, to such a height that the abutment 22 cannot possibly engage the tread surface of the heel of a shoe to be jacked. At this time also the jacking spindle 26 is in its lowermost position, the abutment 24 being spaced substantially from the adjacent portion of the last. The shoe is presented to the positioning fingers 50 and 52, toe foremost, causing the fingers to separate and to slide along the crease between the sole and the upper until their final position in the crease adjacent to theheel breast corners as determined by the members I6 and 18 is reached. It is to be understood that at the time when the shoe is thus placed in the jack it is at the loading station of the machine where there is no operating instrumentality to interfere with the above-described movement of the shoe. With the shoe thus supported by the fingers 50 and 52, it is pushed so as firmly to hold the heel breast against the members 16 and 18, thereby causing the longitudinal axis of the shoe to be alined with that of the jack. The forepart-engaging abutment '|2 is now positioned, by making up the set screw 14, at such a height that the plane of the rand crease is perpendicular to the axis of rotation of the jack which passes through the middle of the heel part of the shoe. It is now .apparent that when the shoe is held in contact with the aforesaid positioning members it is definitely located heightwise and laterally by the fingers 50 and 52 and the abutment 12 and angularly by the members 16 and 18. Moreover, all other shoes of the type for which the .aforesaid adjustments have been made will be so positioned that the rand or rand crease always occupies the same position. After the shoe has been thus positioned, the nut 92 is turned to bring the abutment 22 in proximity to the tread surface of the heel. The wedge |04 is then moved to the left from its position as illustrated in Fig. 1 to cause the abutment 22 to be pressed firmly into engage- ,y

meni-l with the heel. The shoe is then ready to receive jacking pressure, which is imparted by raising the jacking spindle 26, thereby causing the spring 21 to be compressed after the clamping abutment 24 has come in contact with the heel part of the last opposite the abutment 22. Jacking pressure may be applied to the spindle 26 by any suitable means, preferably by the use of mechanism such as preferred to above and disclosed in the above-mentioned Letters Patent.

vIf the operating tools, the rand-burnishing tool and the indenting wheel, are not at such a height as to engage the portion of the heel to be operated upon when swung into engagement with it, they are first adjusted heighthwise by adjusting the position of the block on the end of the arm 42. As the tools are swung toward the heel surface to be treated owing to the action of the spring 44, the guide |42 first engages the peripheral surface of the heel and causes the bearing member |22 to be swung until the indentlng tool engages the heel surface, at which instant the wheel at the operating point has complete heightwise contact with the heel surface to be indented. At the same time the lip |44 of the rand-burnishing tool` 34 enters the rand crease nishing of the rand is provided. The other'component of the pressure ofthe member 39, namely that extending transversely with respect to the tothe shaft 3,8', is utilized to force the operative surface of the indenting wheel 32 into `the peripheral surface of the heel far enough to form the required indentations. As the shoe is moved to cause the Ipoint of operation ofthe tools to be transferred about the heel, the rand-burnishing tool 34 is oscillated rapidly owing to the rotation of the drive shaft' 38, but the indenting Wheel merely rolls idlyY in its bearing member im while swinging also about a tangent to its surface at the operatiing point as an axis owing to the coaction of the guide |42 which also rolls along the heel surfacebeing operated upon but at a pointremote from the operating point of the tool. At the conclusion of the indenting and burnishing operation the link 4,6 is moved outwardly of the machine by mechanism such, for

Cai

example, as that described in the above-mentioned Letters Patent, to move the operating tools away from the shoe inpreparation for the next movement of the jack `carrier It,A which will bring another shoe into position to be operated upon. i

While the present invention is concerned with `an improved heel-burnishing and indenting device and an ,improved work jack which positions the shoe, by engaging the rand, relatively to a tool for operating on the randA itself, itis to be understood that the invention, in the indent- Y ing aspect, may have applicationV to an indenting" `device to which the `work is presented by hand,

"and that the invention in the work'jack aspect v may have application in a machine in which it is desired to jack a shoe so that `the heel is located in predetermined Vrelation with respect to a `tool for operatingupon vanypart or the whole 1 of its peripheral surface;
